ROLLER-BEARING.

SPECIFICATIONformng' part of Letters Patent No. 709,441, dated September 16, 1902. Original application filed July 20,*1901, Serial No. 69,151. Divided and this application iiled June 5, 1902. Serial roller-bearings,and is adivisional application of my application for Letters 'latent upon roller-bearings filed July 20, 1901., Serial No. 69,151.

This invention relates to an antifriction roller-bearin g for rotatable shafts mounted in stationary journal-boxes or for a wheel rotay tably mounted on a stationary shaft or axle;

of one of the antifriction-rollers.

and the object of the invention is to so construct a bearing that therewill be practically no friction between the journal and the antifriction-rollers when the parts are in motion and also to provide a means for adjusting the parts relatively to each other to prevent longitudinal, radial, and lateral displacement.

In the drawings, Figure l is a sectional view of the roller-bearing, showing the relative position of the parts. Fig. 2is a sectional view of a modification. Fig. 3 is an enlarged View Fig. 4 is an enlarged sectional view through one of the bearing or retaining rings. Fig. 5 is an enlarged sectional View of the axle and sleeve shown in Fig. 2.

Like letters of reference refer to like parts through the specification and drawings.

In Fig. 2 the axle a is shown to be fitted with sleeves or boxings h, prevented from inward displacement by abutting flanges o, integrally formed With the axle ci at the inner ends of the seats therefor and abutting and projecting slightly beyond the periphery of the sleeves or Vboxings b. Encircling the axle ct are two sets of bearing or retaining rings d, in the inner faces of which are formed conical recesses e, terminating in horizontallydisposed openings or bores f, parallel with the axis of theshaft or axle a. Contained between the bearing or retaining rings are antifriction-rollers g, having tapering man- (No model.)

drels 471 terminating abruptly in conicalshaped ends t'. When the antifriction-rollers `and the bearing or retaining rings are assembled, Lhe conical-shaped ends i are contained in the recesses e, the points of the ends i being opposed to the boresf, so that the contact between the ends of the mandrels and the Arings will not be upon the points of the mandrels, but as near thereto as will render the contact substantial, and as the recesses e are vof much greater diameters than the ends of the Inandrels it follows that there will be no contact other than that near the points. Unit- `'ing retaining or bearing rings are tie-rods j, having shoulders c engaging the inner faces lof the retaining-rings and the usual screwthreaded shanks, which pass through the rings and are fitted with nuts Z, engaging .is screw-threaded, and mounted on the screwthreaded parts are nuts m, the inner faces of which are recessed to provide outwardly-projecting lianges o to contact with the ends of the roller g.

By reference to the drawings it will be noticed that the ends of the rollers gare correspondingly recessed. Theobject ofthis construction is to minimize the contacting snrfaces thereof with those of the nuts m. The

`abutting flanges c engaging the inner ends and the nuts m engaging the outer ends of the rollers hold the rollers in an adjusted position on the sleeves or boxings b. Inclosing the rollers g and the retaining-rings d is the shell p of the hub, the inner faces of the ends of which are screw-threaded, and contained in the hub-shell p is a centrallylocated lining q, having annular abutting flanges r, the side faces of which are disposed in the same planes as the side faces of the abutting flanges c, the purpose of the flanges r being to assist the flanges o in resisting the inward displacement of the rollers, the rollers contacting with the adjusting-nuts and preventing the outward displacement ot' the hub-shell. Contained within the hub-sehll are antifriction-linings s,opposed to the antifrictiou sleeves or boxings b. The antifriction-rollers g engage the sleeves b and linings S during the rotation of the wheel or axle and revolve collectively with the bearing or retaining rings about the shaft or axle, each antifriction-roller during such collective revolution revolving individually on its own axis. Contained in the threaded ends of the .hubshell j) are annular nuts t, the inner faces of which are fitted with annular flanges u, bearing against the outer ends of the antifrictionrollers g. When assembled in position, the nuts tare alined with the nuts m, and formed in the nuts fm, and tareannular recesses e, in which are contained the adjacent rings d, there being sufficient clearance between the rings and nuts to prevent any contact between them. Fitted in the ends of the hub or sleeve p are llock-nuts w, bearing against the nuts t, and formed in the nuts w and 1',

are annular recesses x, in which are contained washers z. Instead of using the sleeves or boxings the axle may be fitted with enlargements a', as shown in Fig. l, with which engage the antifriction-rollers g.

Having thus described lnyinvention, what I desire to secure by Letters Patent isl. In a roller-bearing, the combination ot' an external hub-shell having internal annular flanges, an axle having integral peripheral lianges lalining substantially With the annular flanges ot' the hub-shell, bearing-rings having conical recesses terminating in horizontally-disposed bores, tie-rods having abutting shoulders engaging the inner faces and nuts engaging the outer faces of the bearingrings, bearing-rollers having` tapering mandrels terminating in abruptly-conical ends journaled in the conical recesses, antifrictionsleeves contained within the hub-shell encircling and contacting the bearing-rollers, and antifriction-sleeves mounted on the axle encircled by and contacting the rollers.

2. The combination of the hub-shell having internal annular flanges, an axle having integral peripheral flanges alining substantially with the annular flanges of the hubshell,bear ing-rings having conical recesses terminating in horizontally-disposed bores, tie-rods having abutting shoulders engaging the inner faces and nuts engaging the outer faces of the bearing-rings, bearing-rollers having tapering mandrels terminating in abruptly-conical ends journaled in the conical recesses, and antifriction bearing-surfaces for the rollers.

roegiai 3. The combination of the hub-shell having internal annular flanges, an axle having integral peripheral flanges alining substantially with the annular fiange of the hub-shell, bearin g-rin gs having conical recesses terminating in horizontally-disposed bores, tie-rods for uniting the bearing-rings, bearing-rollers having recessed ends fit-ted with tapering inandrels terminating in abruptly-conical ends journaled in the conical recesses, antifrictionsleeves contained within the hub-shell encircling and contacting the antifriction bearingrollers, and nuts fitted on the axle and into the ends of the hub-shell having on their inner faces annular flanges contacting with the ends of the bearing-rollers.

4.' The combinat-ion of a hub-shell having internal annular flanges, an axle having integral peripheral iianges alining substantially with the anges of the hub-shell, bearingrings having conical recesses terminating in horizontally-disposed bores, tie-rods having abutting shoulders engaging the inner faces and nuts engaging the outer faces of the bearingrings, bearingrollers having recessed Vends fitted with tapering mandrels terminating in abruptlyconical ends journaled in the conical recesses, antifriction sleeves contained within the hub-shell encircling and contacting the bearing-rollers, antifrictionsleeves mounted on the axle encircled byand contacting the bearing-rollers, nuts fitted on the axle and into the ends of the hub-shell having on their inner faces annular flanges contacting the ends of the bearing-rollers.

5. The combination of the hub-shell having internal annular flanges, an axle having integral peripheral anges alining substantially with the flanges ot' the hub-shell, bearingrings having conical recesses terminating in horizontally-disposed bores, tie-rods uniting the bearing-rings, bearing-rollers having recessed ends fitted with tapering mandrels terminating in abruptly-conical ends journaled in Ithe conical recesses, antifriction-sleeves contained Within the hub-shell encircling and contacting the bearing-rollers, antifrictionsleeves mounted on the axle and encircled by and contacting the bearing-rollers, and nuts fitted on the axle and into the ends of' the hubshell having on their inner faces annular flanges contacting with the ends of the bearing-rollers.

In testimony whereof I affix my signature in presence of two witnesses.
